If OPL is assigned to OAC, the motor phase loss detection is not used to manage the fault but to detect that the contactor is opened.

When the drive detects that the contactor is opened, it doesn’t trip but it reduces the output voltage to avoid an over-current when the contactor is closed again.

Therefore, when the drive detects that the contactor is closed again (output current is increasing) then the catch on fly function is performed (smooth restart).

No detected error triggered, but management of the output voltage in order to avoid an overcurrent when the link with the motor is re-established and catch on the fly performed (even if this function has not been configured).The drive switches to [Output cut ]SOC state after [OutPhL Time] Odt time. Catch on fly is possible as soon as the drive is in stand by output cut [Output cut] SOC state.
